title: A screening method for autoregulators of anthracycline-producing streptomycetes.
abstract: A novel method was proposed for screening of autoregulators by anthracycline-producing strains of Streptomyces griseus. By means of a modified cosynthesis procedure, an indicator strain was detected capable of producing both leukaemomycin and aerial mycelium only in the presence of specific inducing factors (autoregulators) which were produced not only by anthracycline-yielding organisms and their mutants, but also by a streptomycin-producing strain of Streptomyces griseus as well as by its non-differentiating derivative.
